Good question, I too am curious to know the answer. I also would like to know how much the Ambulator shoe will retail for. Could you imagine if Aetrex sells 100,000 shoes next year, which is not a lot. Not sure how much GTX will charge for the monthly subscription fee but say it is $5. That is $500,000 per month GTX gets at say 90% margin. This Aetrex deal could turn into a cash flow machine for GTX.
